Five new species of lichenicolous conidial fungi from Spain are described. The genus Lichenohendersonia Calatayud & Etayo gen.nov. is introduced to accommodate three new coelomycetes: Lichenohendersonia squamarinae Calatayud & Etayo sp.nov. (on Squamarina lentigera), Lichenohendersonia uniseptata Etayo & Calatayud sp.nov. (on Parmelina tiliacea), and Lichenohendersonia varians Calatayud & Etayo sp.nov. (type on Rhizoplaca chrysoleuca, but also occurring on other saxicolous crustose lichens). Two further species are also described: Phoma aggregata Calatayud & Etayo sp.nov. (on Diploschistes ocellatus), with numerous and densely aggregated pycnidia, and Feltgeniomyces dichotomus Etayo & Calatayud sp.nov., a sporodochial fungus occurring on Physcia biziana and Heterodermia sp. All these taxa are known only from the Iberian Peninsula, except F. dichotomus, which is also reported from Colombia. Keys to the known Feltgeniomyces and Lichenohendersonia species are provided.Key words: Lichenicolous fungi, deuteromycetes, Feltgeniomyces, Lichenohendersonia, Phoma, Spain.
